Old and tired and past its glory days. There is one way for the Plaza to improve and its called implosion followed by sterilization.
The only thing good about this place is that it has a really good location in downtown and the prices for room nights are dirt cheap. Its good if you're the kind of tourist that plans to gamble and eat elsewhere all day and all night...get so piss drunk that when you stumble back to your room at 6am you don't realize how nasty this place is.
Golden Nugget is close by and just a tad bit pricer, and looks like the fricking Ritz Carlton compared to this dump.
